Not commenting on the specific design, but I'd rather not have a chance
for a pressure vessel to burst when I'm working on it. Seems to me that
it would be better to lose the vehicle due to the deployment system not
working than take a chance on getting injured.

If I am reading this correctly, you have a burst-disk to ambient between the source and the valve.
By adding this you are choosing that in the case of an overpressure during flight, rather than leaking through the valve or causing a small explosion, the deployment system will disarm itself and the rocket will become a ballistic, energetic impactor.
I am guessing that all components have large margin against rupture due to over-pressure, so unless you have severe concerns about safety during ground operations, why include it? I would lean on the side of "blow it out or blow it up" if it were my project. But I may be missing something important.

One benefit of this weekly blogging is that it requires me to get
something done at least once a week.
